Question

C.
A body is situated at the height of 20 m from the ground. The potential energy of
body is 100 J. Calculate the mass of body. (Given, g = 10 m/sec)​

Answer 1

$\huge\underline\mathfrak\pink{Answer}$

$\huge\boxed{Mass\:=\:0\:.\:5\:kg}$

$\huge\underline\mathfrak\pink{Explanation}$

Given :

Potential energy = 100 J

g = 10m/s²

Height (h) = 20m

To find :

Mass = ?

Solution :

We know that,

Potential energy = mass × acceleration × height

PE = mgh

Now put the given values :

100 J = m × 10m/s² × 20m

100 J = m × 200

200m = 100

m = 100/200

m = 1/2 = 0.5 kilogram. [ Required answer ]
